involved in the production and circulation of immunoglobulins
this molecule displays 'self' peptides on the surface of all endogenous cells.
central artery is located in the middle of _____ pulp.
any substance that can generate an immune response
membrane bound forms of immunoglobulins on B cells that serve as antigen specific binding site
prevents foreign antigens from reaching thymocytes
These cells are CD4+.
injected antibodies are a form of what type of immunity?
these cells are the basis for immune memory
which T cells attack non-specific epitopes?
which cells express MHC II?
inner core of the lymph node
outer portion of the lymph node
these serum proteins function to coat pathogens for phagocytosis and recruitment of phagocytic cells to the site of infection.
involved in the filtration of the blood
these lymphocytes differentiate in the thymus and they account for the majority of circulating lymphocytes
These T cells express CD8 and function to kill target cells.
lymphocytes become immunocompetent in ____ lymphatic organs.
MALTs are found in the ____ ____ of ailmentary canal, respiratory tract, and GI tract.
immunity that does not depend on immune recognition by lymphocytes
this specific type of helper t-cells interact with B-cells and are essential in initiating antibody mediated immune responses
this molecule presents partially digested endocytosed foreign peptides to helper T-cells.
pre-existing defense such as skin and low pH of stomach, constitute which type of immunity?
QuestionAnswer
these cells rapidly secrete antibodies (immunoglobulins)
true or false: epithelioreticular cells are connected via desmosomes.
MALT stands for what?
corona contain primarily which lymphocyte?
defenses that target a specific antigen or foreign agent
bone marrow, GALT, and thymus are identified as ____ lymphatic organs.
Lymphocytes undergo antigen-dependent activation in ______ lymphatic organs
TCR
lymphocytes conveyed in blood enter lymph nodes via _____ ______ _____.
these vessels convey lymph toward the lymph node and enter it at various points on the convex surface of the capsule.
true or false: epithelioreticular cells secrete reticular fibers.
germinal centers contain primarily which lymphocyte?
dense connective tissue, which extend from the capsule to the substance of the node, forming a gross framework
